Asterix
Programming
The Asterix board provides a B2B (Board-To-Board) connector that gives access to:
- MCU VDD, VUSB and GND
- MCU SWCLK, SWDIO and RESET
- Debug UART RX/TX
The connector part number is Molex 5050040812, and the pinout is as shown below.

Asterix B2B connector pinout
The "Core B2B v2" board has been designed as a companion programming board.
It is based on the Raspberry Pi Debug Probe.
Software for the Core B2B v2 board is available in the Core B2B v2 repository.
Below you can find a picture on how it is connected, and a list of its main features.

Asterix and Core B2B v2
External connectors (SWD/UART) expose 1.8V signals.
Do not use any adapter that does not operate at 1.8V, or there is a **risk of damage**!
